Figure Lengend Snippet: Figure 6. α-Casein (A), β-CN (B), and κ-CN (C) peptide fragments hydrolyzed by calf rennet, ES6023 milk-clotting enzyme (MCE) and DB219 MCE on SDS-PAGE. Lane M: protein marker, lane a: α-CN, lane b: β-CN, lane c: κ-CN, lane 1: calf rennet, lane 2: ES6023 MCE, lanes 3 to 6: DB219 MCE. The α-CN/MCE, β-CN/MCE, or κ-CN/MCE ratios were 15:1 in lanes 1 and 2, 5:1 in lane 3, 10:1 in lane 4, 15:1 in lane 5, and 30:1 in lane 6. GMP = glycomacropeptide.
Article Snippet: Figure 3C shows that Ca2+, Co2+, Mn2+, and Li+ significantly increased the DB219 MCE MCA to about 109, 124, 128, and 193% at 0.25 M, respectively.
